<u>Answer:</u> The correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate
<u>Explanation:</u>
We are given:
Average number of drops of sodium bicarbonate = 142
The chemical equation for the reaction of sodium bicarbonate and acetic acid in vinegar follows:
From the stoichiometry of the reaction:
1 mole of sodium carbonate reacts with 1 mole of acetic acid in vinegar.
Hence, the correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate
Answer:Atomic size generally increases within a group and decreases from left to right across oa period. When do ions form? Ions form when electrons are transferred between atoms.
Explanation:
Answer:
A. The atoms have more energy together than separated.
Explanation:
There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.
Atoms with lower forces typically don't typically bond with other atoms of lower forces.
Answer:
C
Explanation:
because valence electrons are located at the last energy level
Answer:
Temperature
Explanation:
The kinetic energy is proportional to the temperature. That is, temperature is a measure of the kinetic energy of atoms and molecules that are part of a system.
This can be explained by kinetic theory.
